MECHANISM OF ACTION
SLU-PP-332 is a small molecule agonist of ERRα, ERRβ, and ERRγ (estrogen-related receptors) - nuclear receptors that regulate mitochondrial biogenesis, fatty acid oxidation, and oxidative phosphorylation gene networks. Activation mimics the transcriptional response to prolonged aerobic exercise without physical activity. Research in rodent models demonstrates enhanced endurance, increased mitochondrial density in muscle, and improved metabolic parameters. Unlike traditional performance peptides, SLU-PP-332 works via nuclear receptor transcriptional activation rather than hormonal pathways.
RESEARCH APPLICATIONS
- Exercise mimetic research - endurance and VO2 max modelling
- Mitochondrial biogenesis upregulation
- Fatty acid oxidation and metabolic efficiency
- Heart failure and muscle wasting models
- Combination with AMPK activators (MOTS-C)
RESEARCH HIGHLIGHTS
Endurance Enhancement in Mice
2023SLU-PP-332 (4 weeks, 100mg/kg IP) increased running capacity by ~70% vs. controls and upregulated PGC-1α, VEGF, and oxidative metabolism genes in skeletal muscle.

ERR Trifecta Agonism
2023Structural studies confirm simultaneous agonism at ERRα, β, and γ - activating a broader transcriptional programme than selective ERR agonists.
